Discussion

Modiola caroliniana is somewhat weedy but not a serious agricultural weed. It has been reported in Delaware, Massachusetts, New Jersey, and Pennsylvania as a waif but doubtfully persists that far north. It is well established in the southeastern United States and is rather common as a lawn weed in some locations and as a garden weed in California. It probably came from southern South America in wool or cotton. Its closest relative, Modiolastrum K. Schumann, is known from southern South America.
